Science (086) — AI-generated practice question

Blocking the vas deferens (vasectomy): The vas deferens carries sperms from the testes to the urethra. Blocking it prevents sperm from being transferred during intercourse, so fertilisation cannot occur.

Blocking the fallopian tube (tubectomy): The fallopian tube carries the egg from the ovary to the uterus, and is where fertilisation normally takes place. Blocking it prevents the egg and sperm from meeting.

Common feature (beyond preventing pregnancy): Both are surgical procedures, and both carry the risk of infection or complications if not performed properly.

• The key distinction examiners want: vas deferens blocks sperm transport (male side); fallopian tube blocks egg transport (female side). State why each prevents fertilisation, not just that it does.
• The "one thing in common" — the passage explicitly states both use surgical methods and both carry the risk of infection. This is the safest answer to use.
• Don't confuse vasectomy with castration, or tubectomy with removal of ovaries — the organs still function; only the pathway is blocked.
